骨盆三维重建及测量在直肠癌手术中的应用

Applications of Pelvic 3D Reconstruction and Dimension Measurement to Colorectal Cancer Surgery

目的帮助医生进行诊断、术前预测和实际手术操作,提出一种三维重建、测量的方法。方法利用直肠癌患者的CT扫描结果建立骨盆三维模型,回顾性分析97例中低位直肠癌患者的影像资料,最后进行统计学分析。结果经过对测量数据进行多因素分析,找出几组影响中低位直肠癌保肛手术关键性的解剖限制性因素。结论应用骨盆三维模型可以获得传统骨盆测量学没有提出的解剖径线和空间测量数据,能更加客观地评价骨盆的解剖因素对保肛手术乃至盆腔手术的限制性作用。

Objective Describes the methods of 3D reconstruction and dimension measurement in order to help doctor in diagnosis, operation planning and the actual surgery. Methods With the help of the CT scan results, we established threedimensional digital model of pelvis. The data of 97 cases of middle and lower rectal cancer patients were retrospectively analyzed and statistically managed. Results With multivariable analysis of the measurement data, we found the anatomic factors that were key to sphincter-preserving operation for middle and lower rectal cancer. Conclusion The application of three-dimensional digital model of pelvis can bring the surgeons new anatomic diameter and spacial measurement data, and thus give more objective evaluation about the critical restrictive role of pelvis anatomy in sphincter-preserving procedure and even in operation of pelvis.
